@Romani TANK-FILLING VALVE.

To all whom t may concern Be it known that I, OLIVER C. Rrrz- VVOLLER, citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Tank-Filling Valves, of which the following is a specification, reference being had to t-he accompanying 'drawings This invention relates to an improved lilling valve for fluid tanks or reservoirs and has for its primary object to provide a simple and novel device of this character embodying in its construction a'casing connected by a pipe or conduit with the tank, and a valve arranged within said casing and yieldingly held in closed position, said valve being displaced from its seat by the insertion of the neck of a funnel within said casing.

Still another object of the invention is to provide improved means for securely closing the valve casing and thus prevent the entrance of dust or dirt into the same and upon the valve or its seat.

A further object of the invention resides in the provision of improved means for mounting the valve member including a casing, and a longitudinally tapering seat member threaded within said casing whereby the same together with the valve may be readily removed.

Another object of the invention is to provide improved means for holding the filling funnel in position to retain the movable valve member out lof engagement with vits seat.

A still further object of the invention is to generally improve and simplify the construction of devices of the above character to increase their efficiency and to minimize the cost of manufacture.

lVith the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations, and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention,

Specification of Letters Patent.

Application led February 27, 1913.

Patented Feb. 24, 1914. Serial No. 751,132.

reference is to be had to the following descrlption and accompanying drawing, in Which- Figure 1 is a side elevation partly in section showing a tank filling valve embodying the present invention; Fig. 2 is an enlarged vertical section of the valve; Fig. 3 is a section taken on the line 3-3 of Fig. 2. Fig. 4 is a detail view partly in section, showing the valve member after it has been removed from its seat by the insertion of the funnel. Referring in detail to the drawing, 5 designates a tank or reservoir to contain gasolene or other fluid, and 6 indicates a short pipe or nipple which is threaded in the wall of said tank.

My improved filling valve includes in its construction, a cylinder or casing 7 provided adjacent to one end with a threaded boss or extension S for engagement upon the eX- teriorly threaded end of the nipple 6 as shown. The other end of the cylinder or casing 7 is provided with interior screw threads to receive the threaded end 10 of a sleeve 9. This sleeve gradually tapers to its other end as indicated at 11 and terminates at a point adjacent the outlet opening in the casing wall into which the nipple 6 is threaded. This inner reduced end of the sleeve 9 is provided with an annular valve seat 12 upon which the disk valve 13 is yieldably held by means of a light coil spring 14. This spring is disposed upon a tubular boss 15 integrally formed with the lower end of the cylinder or casing 7 and bears at its upper end against the under side of the valve disk 13. This disk is provided with a short stem 16 which is disposed within the tubular boss 15 and guided thereby. The valve disk 13 is provided upon its upper surface with a spider 13 which may be either integrally formed therewith or secured to the same in any preferred manner. This spider consists of a plurality of intersecting arms secured at their outer edges to the surface of the disk and extending inwardly and upwardly at an oblique angle to a point above the center of the disk. Y The bottom wall of the casing 7 is preferably provided with a suitable drain cock indicated at 17 whereby the oil collecting in said casing below the nipple may be drained therefrom.

A cap plate or cover 1S is hingedly mounted between spaced ears 19 formed upon or secured to the upper end of the casing 7. Upon the ends of the hinge pintle 20, the coils of a heavy spring wire 21 are engaged. The ends of this wire are suitably fixed to the casing from which. the ears 19 are formed. while the intermediate portion 22 thereof is Secured to the under side of the cap plate or cover 18. This spring acts to normally hold the cover 18 in close engagement with the upper end of the casing wall 7, said cap plate being of slightly greater diameter than the casing so that the same will overhang the casing wall. This cap plateis preferably provided with a suitable finger piece 23 whereby the same may be lifted. To the upper end of the valve seat member 9 and upon the inner surface thereof, a horizontally disposed bowed leaf spring Q5 is secured at its center. The arms of this spring are adapted to embrace and frictionally engage the neck or spout of a filling funnel, indicated at 211.

ln the use of the device, the spout or neck of the funnel 24E is inserted through the sleeve of the valve seat member 9 which is arranged within the casing 7 until the sam-e engages the spider 13', carried by the valve disk 13. The end of the funnel spo-ut forces the valve member from its seat and holds the same against upward movement by the `action of the valve spring la. The arms of the bowed leaf spring 25 engage the neck or spout of the funnel adjacent its upper end1 and hold the same in position, thus relieving` the operator of the necessity of holding` the funnel with his hand to retain the valve member out of engagement with its seat. The air which is displaced by the entering fluid will pass upwardly into the space between the tapering sleeve 9 and the wall of the casing 7 and escape through the cock 26 which is open, while the storage tank is being filled. As soon as the funnel is withdrawn, the cover or cap plate 18 is returned to its closed position upon the upper end of the casing by the spring 21, t-hus effectually closing said casing and preventing the entrance of foreign matter into the same to be carried by the gasolene int-o the storage tank or reservoir.

From the foregoing, it is thought that the construction and manner of operation of my improved lling valve will be clearly understood.

The device is particularly designed for use upon gasolene storage tanks such as are carried by automobiles or other motor vehicles, but it will of course, be appreciated that the invention can also be used for many other analogous purposes and is applicable to all fluid storage tanks.

lt will also be obvious that in putting the invention into practical use, many minor alterations or modifications may be found necessary in the form, construction and arrangement of the several elements thereof, and I reserve the right to resort to such alterations as may fairly fall within the spirit and scope of the appended claims.

Having thus described the invention, what is claimed is:
